【Abstract】 Objective To summarize the current development of the correction of severe and rigid scol iosis. Methods Recent l iterature concerning the correction of severe and rigid scol iosis at home and abroad was extensively reviewed, and current developments of the correction of severe and rigid scol iosis were summarized. Results The correction of severe and rigid scol iosis shows developments as follows: the application of Halo-gravity traction increase and Halo-femoral traction is applied in posterior correction surgery. Fixation and correction technique with all pedicle screws was gradually popularized. The applications of posterior vertebral column resection, one-stage anterior and posterior surgery, and posterior-only correction surgery increase. Conclusion The developments of all kinds of correction techniques improve the correction effects of severe and rigid scol iosis. Now there is no standardized treatment protocol for severe and rigid scol iosis. Greater development can be expected in the future.
Objective To elucidate the new development and effects of three-dimensional correction techniques of idiopathic scol iosis (IS). Methods The related home and abroad l iterature concerning three-dimensional correction techniques of IS was extensively reviewed. Results With more and more attention to three-dimensional correction of IS, all kinds of surgery and developed techniques of correction are applied to the correction of IS. The effects of three-dimensional correction of IS are satisfied. Conclusion With more knowledge about IS and more developed theory of correction, more safe and effective techniques of correction is therefore the hot spot for future study.
